This extension provides a rich editing experience for Angular templates, both inline and external templates including:

• Completions lists
• AOT Diagnostic messages
• Quick info
• Go to definition
• Document Symbols for Outline panel, breadcrumbs, and "Go to Symbol"

Download the extension from Visual Studio Marketplace.

The Angular Language Service uses the same set of options that are used to compile the application. To get the most complete information in the editor, set the strictTemplates option in tsconfig.json, as shown in the following example:

"angularCompilerOptions": {
  "strictTemplates": true
}

For more information, see the Angular compiler options guide.

Document Symbols enable the Outline panel, breadcrumbs navigation, and "Go to Symbol" (Cmd+Shift+O / Ctrl+Shift+O) to show Angular template elements like @if, @for, structural directives, and template references.

For TypeScript files with inline templates, the Outline shows only the component class with template symbols nested inside:

MyComponent (class)
└── (template)
    ├── @if (condition)
    └── <button>

Example configuration:

{
  "angular.documentSymbols.enabled": true,
  "angular.documentSymbols.showImplicitForVariables": false
}

The language service extension relies on the @angular/language-service and typescript packages for its backend. @angular/language-service is always bundled with the extension, and is always the latest version at the time of the release. typescript is loaded, in order of priority, from:

1. The path specified by typescript.tsdk in project or global settings.
2. (Recommended) The version of typescript bundled with the Angular Language Service extension.
3. The version of typescript present in the current workspace's node_modules.

We suggest not specifying typescript.tsdk in your VSCode settings per method (1) above. If the typescript package is loaded by methods (1) or (3), there is a potential for a mismatch between the API expected by @angular/language-service and the API provided by typescript. This could lead to a failure of the language service extension.

For more information, please see #594.

Download the .vsix file for the release that you want to install from the releases tab.

Do not open the .vsix file directly. Instead, in Visual Studio code, go to the extensions tab. Click on the "..." menu in the upper right corner of the extensions tab, select "Install from vsix..." and then select the .vsix file for the release you just downloaded.

The extension can also be installed with the following command:

code --install-extension /path/to/ngls.vsix

• coc-angular for (Neo)vim
• nvim-lspconfig for Neovim
• Wild Web Developer for Eclipse
• lsp-mode for Emacs

The Angular Language Service provides inlay hints for templates, showing inline type annotations directly in your code. This feature helps you understand types without hovering over variables.

<!-- @for loop variables -->
@for (user /* : User */ of users; track user.id) { {{ user.name }} }

<!-- @if aliases (simple and complex) -->
@if (currentUser; as user) { {{ user.name }} }
@if (currentUser.profile; as profile /* : Profile */) { {{ profile.name }} }

<!-- @let declarations -->
@let count /* : number */ = items.length;

<!-- Template references -->
<input #emailInput /* : HTMLInputElement */ />

<!-- Event bindings -->
<button (click)="handleClick($event /* : MouseEvent */)">
  <!-- Property bindings -->
  <app-child [data /* : Data */]="myData"></app-child>
</button>

All inlay hints settings are under angular.inlayHints.*:

To disable all Angular inlay hints, you can set editor.inlayHints.enabled to "off" in your VS Code settings.
